, the following detailed description, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views and.

wherein:

Figure l is a top plan view of my electrical connector. i Figure 2 is a vertical sectional view, taken substantially on the' line 2-2 of Figure l.

Figure 3 is a top plan view of another form of the device.

Figure 4 is a vertical longitudinal sectional view, taken substantially on the line -t of Figure 3.

Figure 5 is a fragmentary sectional view, taken substantially on the line 5--5 of Figure 4.

Figure 6 is another form of the device. Figure 7 is a vertical longitudinal sectional View, taken substantially on the line l--l of Figure 6.

Figure 8 is a vertical sectional view through still another form oi the device. l Referring now io the drawing in detail, it win be seen that the reference numeral Ill designates a substantially rectangular block constructed of insulating material, said yblock having a groove II in its top adjacent one side thereof. The groove II is formed to provide a substantially tapered well II' having a substantially iiat bottom which has an opening I2 therethrough, said opening communicating with a socket I3 in the 5 bottom of the block. Mounted in the body of the block I0 adjacent the groove II is a connector fitting I4 having lead wires I5 and I6 which are embedded in said block IIJ withtheir ends I'I and I8 sharpened and projecting into the Wellv 50 II. A wedge member I9 is engaged in the well II' and is held therein by a bolt 20 which passes through the wedge I9 and has threaded thereon a retaining nut 2I in the socket I3 for drawing the wedge into the well II' to force the ends of 55 the wires 22 and 23, which are seated in the of electrical conductors.

groove II, to be impaled on the pointed projections I1 and I8.

The form of the device shown in Figures 3, 4 and 5 of the drawing comprises a block 24 having a groove 25 at one side portion thereof, an inter- 5 mediate portion of which is of greater depth, as at 26, to provide a well for the end portions of conductor wires 2l and 28. The wires 2l and 28 are held in the well 29 through the medium of a wedge 29, said wedge 29 having a recess formed l0 in the upper portion of one side thereof, as at 30, which receives a nut 3l for holding the wedge 29 in the groove 25 through the medium of a screw 92. Thus, the wedge 29 holds the wires 21 and 28 impaled on the sharpened projecting l5 end portions 33 and 34' of the wires 33 and 3Q which are connected with the conventional fitting 35.

In the form of the invention shown in Figures s and 7 of the drawing the mock as is construnt- 20 ed to provide for the joining of the ends of pairs In this form the block 36 has formed in the top thereof a groove 3l which has its intermediate portion of greater depth to provide a well 3l for receiving the 25 end portions of pairs of wires 38 and 39 which are forced therein through the medium of a wedge 40 and bolt Il which passes through said wedge 40 and extends through an opening in the bottom of the block et io receive a nut i2 and 3 hold the wedge 46 securely in place.

. The wedge t has extending lengthwise therethrough conductor wires 0' which terminate in projecting points ,40" which penetrate the wires 33 and 39 for providing an' electrical connection 35 therebetween. I

The form of the invention shown in 'Figure 8` comprises a shell d3 having a substantially tapered Well therein, as at d5, in which the end portions of wires t5 and d6 are impaled and secured by the pointed, projecting end portions t6 of .a conductor 56 in a wedge member 4l. The member tl has a recesst formed in one side thereof for receiving a nut 4 9 which is threaded 4,5 on a screw for holding the device assembled.

From the foregoing it can readily be `seen that an electrical connector of this character may be quickly and easily employed to connectthe ends of electric wires with a minimum of eiort to 50 secure an eflicient connection. This is accomplished by merely placing the ends of the wires in the groove portion of the block in opposed relation and then causing the wedge to force the wires against the impaling conductor andthere- '55 by bridge or connect the ends of the electric Wires.

Although I have shown and described herein preferred embodiments of my invention, it is to be denitely understood that I do not desire to limit the application of the invention thereto,

and any change or changes may be made in the materials and in the structure and arrangement of the several parts, within the spirit of the invention as claimed.

What is claimed is:

1. In a connector, an insulating block having a longitudinal groove therein, the groove being `of greater depth through the intermediate portion thereof and having inclined longitudinal ends leading substantially to the surface of the block, conductive pin members projecting into the groove and mounted in the inclined ends of the groove, insulated wires having the ends thereof projecting longitudinally into the groove, and so arranged as to engage the pins, the pins being connected by electrically conductive means, and an insulating Wedge having an intermediate portion and inclined ends shaped to correspond to the longitudinal profile of the groove, said wedge holding said pins pierced in said wires and in contact with the conductors thereof, and means to secure said wedge in holding position.

2. In a connector, an insulating block having a longitudinal groove therein, the groove being of greater depth through the intermediate portion thereof and having inclined longitudinal end portions leading to a point adjacent the surface of the block for the reception of the end portions of a pair of insulated conductor Wires, conductive pin members mounted in the block and projecting into said endportions of the groove for penetrating the insulated Wires, conductive means electrically connecting said pin members, a wedge having an intermediate portion and inclined ends shaped to correspond to the longitudinal profile of the groove, said wedge being engageable with the conductor wires for holding said wires impaled on the pin members, and means for securing the Wedge in operative position.

3. In a device of the character described, an electrical conductor connector comprising a block having a groove formed therein and further having a lateral opening therein, pointed members projecting into said groove for contacting wires therein, conductive means connecting said pointed. members, a substantially Wedge shaped member having a notch formed in one side thereof mounted in said groove and contactingV said wires, a screw threaded member engaged in said lateral opening in said block member, and a nut on said screw threaded' member vengaged in said notch to hold said wedge and wires in said groove.

4. In al device of the character described, an electrical conductor connector comprising a block having a groove therein, the groove being of greater depth through the intermediate portion thereof and having inclined longitudinal end portions leading to a point adjacent the surface of the block for the reception of the end portions of a pair of insulated conductor wires, said block further having a lateral opening therein, a substantially wedge shaped member having a notch formed in one side thereof mounted in said groove and contacting said insulated conductorwires, a conductor member embedded in said wedge member, a pin member secured to each end of said conductor member embedded in the wedge member and projecting into the groove and in electrical contact with each of the insulated conductor members, a. screw threaded member engaged in said lateral opening in said block member, and a. nut on said screw threaded member engaged in said notch to hold said wedge and Wires in said groove.
